Description
1) An instrument used to measure the specific gravity of liquids or liquid/solid mixtures. A hydrometer usually has a hollow, sealed graduated tube that is placed in the solution of interest. The tube sinks to a position that corresponds to the density of the liquid. Hydrometers are used to compared the density of glazes and to ensure consistency from batch to batch.
2) An instrument used to measure the velocity of moving water.
